Dalmatian Stone (Felsic Igneous Rock)

Painted River Rock

Artificially Coated Sedimentary Rock

Gemstone Ring

Various (Likely Glass, Cubic Zirconia, or assorted semi-precious stones)

Green gemstone ring, likely emerald simulant or jade

Uncertain; possible beryl (emerald, Be₃Al₂Si₆O₁₈) or jadeite (NaAlSi₂O₆), but the blurred image may show synthetic glass or another treated stone

Opalite

Synthetic Opalised Glass
